The readily apparent semantic differences result from alternative strategies for interpreting the difficult verse and relate to differences in vowelization and punctuation of the consonantal text.
In this context, strong indicates those verbs that form their past tenses by ablaut (the vocalic conjugations), weak those that need the addition of a dental suffix (the consonantal conjugations).
When necessary, vowels are indicated by diacritic marks above or below the letter representing the syllabic onset, or by use of "matres lectionis", which are consonantal letters used as vowels.
